Select E2 enzymes differentially regulate parkin activation and mitophagy

Abstract excerpt

Loss-of-function mutations in the genes encoding PINK1 and Parkin (also known as PARK2) are the most common causes of recessive Parkinson's disease. Both together mediate the selective degradation of mitochondrial proteins and whole organelles via the proteasome and the autophagy-lysosome pathway (mitophagy). The mitochondrial kinase PINK1 activates and recruits the E3 ubiquitin ligase Parkin to de-energized...
